Abstract In this modern world many communication devices are highly intelligent and interconnected between each other. Any up-gradation of the hardware in the existing communication devices is not easier one. Compatibility of the new hardware with existing hardware is highly essential. But the new protocols may or may not support the older one. The solution for these problems can be provided by using the recongurable hardware design. The hardware can be reprogrammed according to the new change in technology upgradation. The cost of commercially available hardware and software requirements for setting up such a module is very high. This can be solved by using Open source hardware and software such as Universal Software Radio Peripheral (USRP) and GNU Radio. This work demonstrates how the modern analog communication system like Community Radio Schemes and Radio Data System (RDS) and digital communication systems such as Simple Digital Video Broadcasting (DVB) and OFDM based data communication can be developed using the Open source hardware USRP1. This work will be helpful even for rst year level of engineering students to easily implement any communication and control applications with cheaper cost.

1 Introduction
A software radio [9] is a radio system which performs the required signal processing in software instead of using dedicated integrated circuits in hardware. The benet is that since software can be easily replaced in the radio system, the same hardware can be used to create many kinds of radios for many different transmission standards; thus, one software radio can used for a variety of applications.
GNU Radio is an open-source and free development tool which provide signal processing modules to implement radio communication system. It consists of two modules one can do the...
